Black Haze Seeds

Haze Genetics Refined, Potency Delivered

Black Haze seeds bring together two legendary sativa-dominant genetics, Purple Haze and Colombian Gold, into a hybrid that hits 18-22% THC while keeping the cerebral, energetic character that made both parent strains iconic. The result is a strain with serious potency headroom without tipping into the anxiety-prone territory that higher-THC hybrids can produce. Indoor yields of 400-500g/m² and outdoor harvests of 500-600g per plant make this a commercially viable grow, not just a collector's piece.

If you're comparing Black Haze seeds against other Haze-lineage hybrids in the same THC bracket, the Colombian Gold parentage adds a distinctly resinous, golden-trichome quality that sets it apart from standard Purple Haze crosses. Available as Autoflower and Regular seeds, there's a format suited to both controlled indoor operations and outdoor seasonal grows.

Black Haze Seed Types: Autoflower vs Regular

Seed TypeFlowering TimeYieldBest For
Autoflower8-10 weeks from seed350-450g/m² (indoor)Year-round indoor grows, faster turnaround, limited space
Regular8-9 weeks (flowering)400-500g/m² indoor / 500-600g/plant outdoorBreeding projects, outdoor seasonal grows, maximizing yield per plant

When to Choose Autoflower

Black Haze autoflower seeds complete the full cycle in 8-10 weeks from seed, making them the practical choice for growers running multiple harvests per year indoors. The trade-off is a modest yield reduction compared to regular photoperiod plants, but for operations where speed and consistency matter more than peak gram counts, the autoflower format holds up well. Seedsman and Herbies Seeds both carry Black Haze autoflower, giving buyers two reputable sourcing options with different pack sizes and shipping coverage.

When to Choose Regular

Regular Black Haze seeds are the format of choice for breeders working with the Purple Haze and Colombian Gold lineage, since male plants are available for crossing. Outdoor growers in climates with a reliable warm season also get the most from regular seeds, where the 500-600g per plant outdoor yield potential can be fully realized. Crop King Seeds is currently the primary retail source for Black Haze regular seeds, carrying them with a 7.2/10 customer rating.

Where to Buy Black Haze Seeds Online

Seedbank Availability

Four seedbanks currently stock Black Haze seeds for sale. Seedsman and Herbies Seeds both carry the autoflower format, giving buyers two solid options for the faster-cycling version of this strain. Seed City also carries Black Haze autoflower, making it the most widely stocked format across retail sources. For regular seeds, Crop King Seeds is the only current retail source, which is worth factoring into your order timing if regular genetics are the priority for your grow or breeding project.

Comparing the Seedbanks

Crop King Seeds holds a 7.2/10 customer score for Black Haze regular seeds, which is a respectable but not exceptional rating for a moderate-difficulty strain. Given that Black Haze is rated moderate to grow, a seedbank with a strong germination guarantee matters more here than it would for a beginner-proof autoflower strain. Seedsman operates as a multi-breeder marketplace, which means their Black Haze autoflower stock may come from different breeders depending on availability, so checking the listed breeder at the time of purchase is worthwhile. Herbies Seeds and Seed City both offer autoflower stock with competitive pack sizing, and Herbies in particular is known for discreet international shipping, which is relevant for buyers in regions where Haze-lineage strains attract additional scrutiny at customs. When comparing Seedsman versus Seed City for autoflower, Seedsman's loyalty points system can reduce effective per-seed cost on repeat orders.

Value Assessment

At 18-22% THC with a Purple Haze and Colombian Gold pedigree, Black Haze sits in a competitive bracket alongside strains like Super Silver Haze and Amnesia Haze, both of which command premium pricing due to their Haze lineage. Black Haze's 8-9 week flowering time is faster than most pure Haze expressions, which typically run 10-12 weeks, making the per-harvest cost-efficiency stronger. The 400-500g/m² indoor yield is solid for the THC range, and outdoor growers getting 500-600g per plant from regular seeds will find the price-per-gram economics favorable compared to shorter-yielding Haze crosses. Medical buyers should note the 0.1-0.5% CBD range is low but not negligible; if CBD certification is needed, request lab documentation from Seedsman or Herbies, as both carry verified genetics from established breeders.

Black Haze Seeds: Frequently Asked Questions

What's the difference between Black Haze Autoflower and Regular seeds?

Black Haze autoflower seeds complete their full cycle in 8-10 weeks from seed regardless of light schedule, while regular seeds require a photoperiod trigger and run an 8-9 week flowering period after a separate vegetative phase. The practical yield difference is real: regular Black Haze plants can hit 500-600g per plant outdoors, while autoflower plants produce less per plant but allow multiple harvests per year indoors. Regular seeds also produce male plants, making them the only viable option if you're working with the Purple Haze and Colombian Gold genetics for breeding. For straightforward indoor production, autoflower from Seedsman, Herbies, or Seed City is the simpler path. For outdoor scale or breeding, Crop King Seeds is currently the only source for Black Haze regular seeds.

What THC level can I expect from Black Haze seeds?

Verified Black Haze seeds from reputable breeders test at 18-22% THC. This range positions it above mid-shelf hybrids but below the 25-28% ceiling of ultra-high-THC strains like Gorilla Glue or Bruce Banner. The Colombian Gold parentage contributes a resinous trichome density that supports the upper end of that range when grown under optimal conditions. CBD content runs 0.1-0.5%, which is typical for a THC-forward hybrid. If you're buying for medical use and need CBD certification, request lab results from Seedsman or Herbies Seeds, both of whom carry verified Black Haze genetics.

Is Black Haze a good strain for beginner growers?

Black Haze is rated moderate difficulty, which means it's not the right first-time grow for someone who has never managed a cannabis plant. The Purple Haze and Colombian Gold lineage produces plants that benefit from some canopy management experience, and the 8-9 week flowering window requires consistent environmental control to hit the upper yield range of 500g/m² indoors. That said, moderate difficulty does not mean expert-only. A grower with one or two completed harvests under their belt will handle Black Haze without major issues. If you're a first-time buyer set on this strain, the autoflower format from Seedsman or Herbies Seeds is the lower-risk entry point compared to regular seeds.

Where can I buy Black Haze seeds online?

Black Haze seeds are currently available from four seedbanks: Seedsman (autoflower), Herbies Seeds (autoflower), Seed City (autoflower), and Crop King Seeds (regular, rated 7.2/10). Crop King Seeds is the only source if you need regular seeds for breeding or outdoor photoperiod grows. For autoflower, Seedsman offers the advantage of a loyalty rewards system that reduces cost on repeat orders, while Herbies Seeds is a strong option for international buyers who prioritize discreet shipping on Haze-lineage strains. Compare pack sizes and per-seed pricing across all four before ordering, as the same autoflower format can vary in price between Seed City and Seedsman depending on current promotions.
